The iPhone 5 features will include something that’s going to improve its battery (provided the battery is not over utilized by the larger display and LTE features).
40-50% Reduction In Power Consumption
Deep in the code dumps, 9To5Mac reports, there are clear indications of the new type of Broadcom WiFi chip being used – it’s called the BCM 4334, which is a successor to the BCC 4330 65nm used on the iPad. The BCM 4334 40nm will result in about 40-50% reduction in power consumption and will thus help in increasing the standby and talk-time of the iPhone 5. Of course, this increase will probably be offset by larger displays and LTE features on the iPhone 5.
Dual-Band Wifi Direct
Another feature owing to the chip change would be that iPhone 5 will be the first iOS device to be capable of WiFi Direct. Presently, Apple supports dual-band WiFi direct only on the MacBook and iMac range of products. By choosing to let the new iPhone have WiFi Direct capability, Apple will probably let AirDrop into the realm of iPhones.
What This Really Signifies
Does this really signify better battery? More talk-time?
At iPhoneStuffs4u, we think this might not exactly be the case. Take the case of the display – iPhone 5 going to be larger this time, with probably enhanced retina display features. Then there’s going to be the LTE feature – coupled with some great speakers and other features which are going to use up the battery even more.
Apple’s inclusion of Broadcom B4334 is a calculated move – by reducing the Wi-Fi consumption, the power source is distributed to the other demanding features of the iPhone 5. Net result: almost same performance for enhanced features.
